Steps to reproduce -
1) Open Calc.
2) Add a few words with errors to the sheet.
3) Press F7 - spell checker dialog.
4) Hit correct or correct all to correct mistake.
5) Press Ctrl-Z.
And Calc crashes.
Writer and Impress don't crash though.
If it still crashes with latest build, can you get a backtrace: https://wiki.documentfoundation.org/QA/BugReport/Debug_Information
I can confirm with Version: 220.127.116.11.alpha0+ and 4.5; win7
regression, no crash in Version 18.104.22.168
